EVALUATION BOARD
Evaluation boards for the AD8170 and AD8174 are available
that have been carefully laid out and tested to demonstrate the
specified high speed performance of the devices. Figure 28 and
Figure 32 show the schematics of the AD8170 and AD8174
evaluation boards respectively. For ordering information, please
refer to the Ordering Guide.
Figure 29 shows the silkscreen of the component side of the
solder side of the AD8170 evaluation board. Figures 30 and 31
show the layout of the component side and solder side respec-
tively. The silkscreens and layout of the AD8174 evaluation
board are shown in Figures 33, 34, 35 and 36.
Both evaluation boards ship with 75
termination resistors on
their analog inputs and analog outputs. To use the evaluation
board in nonvideo applications where 50
termination is more
popular, these resistors can be replaced with 50
values. The
digital control pins are terminated with 50
resistors to allow
easy connection to laboratory equipment.
The gain of the output current feedback op amp on both boards
has been set to +2. For other gains the two gain resistors can be
easily replaced. Refer to Table III for appropriate values at gains
other than +2.
For connection to external instruments, side-launched SMA
type connectors are provided. Space is also provided on the
board for the installation of SMB of SMC type connectors.
